CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. provisional patent application Ser. No. 62/057,500 filed Sep. 30, 2014, the entire contents of which is hereby expressly incorporated by reference.

BACKGROUND AND SUMMARY

This invention relates to an ergonomic support, and more particularly to a support arrangement for one or both of a user's forearms when working in a defined area with one or both hands, such as when operating a user input or interface device such as a keyboard or the like.

Various attempts have been made to provide comfortable and ergonomically satisfactory operation of user interface devices, such as a computer keyboard. Such attempts have not been entirely satisfactory. For example, a common device employed to relieve hand and arm strain during operation of a computer keyboard is a wrist rest located adjacent the lower edge of the keyboard. While a wrist wrest provides some relief, it nonetheless requires the user to support his or her arms from the shoulders and creates a concentrated pressure point on the user's wrists, which can create finger numbness and shoulder fatigue.

It is an object of the present invention to provide an ergonomically satisfactory arm support for a user during operation of a user interface device that provides significant advantages over the prior art.

In accordance with one aspect of the present invention, a work arrangement includes a work component, such as a user interface device configured to be manually manipulated by a user, and a cushioned support arrangement located between the work component and the user. The cushioned support arrangement includes a cushioned support area configured and arranged to support the user's forearms and wrists during use of the work component. Representatively, the user interface device may be in the form of a keyboard. The cushioned support arrangement may be in the form of a cushion member having a device support area, with the cushioned support area for the user's forearms and wrists being located rearwardly of the device support area. The cushioned support arrangement may be arranged on a work surface having a front edge, and the cushioned support arrangement may be positioned between the front edge of the work surface and the device support area. The cushioned support arrangement may include a front portion that overlies the front edge of the work surface, and the device support area may include a recess within which the device is received. A releasable engagement arrangement may be interposed between the device and the device support area for selectively maintaining the device in position on the device support area.

In accordance with another aspect of the invention, a work arrangement includes a work surface defining an upwardly facing work area, a work component configured to be manually manipulated by a user, and a cushioned support arrangement positioned on or forming a part of the work surface. The cushioned support arrangement is located between the work component and the user, and includes a cushioned support area configured and arranged to support the user's forearms and wrists during use of the work component. The work component may be in the form of a user input or interface device such as a keyboard. The cushioned support arrangement may be in the form of a cushion member having a device support area, with the cushioned support area for the user's forearms and wrists being located rearwardly of the device support area.

In accordance with another aspect of the invention, a method of operating a user interface device includes providing a user interface device having a user input area; supporting the user interface device on a work surface defining an edge, with the user input area of the user interface device being located inwardly of the edge of the work surface; providing a cushioning forearm support between the edge of the work surface and the user input area of the user interface device; and supporting a majority of the length of the user's forearms on the cushioning forearm support while the user operates the user input area of the user interface device. The cushioning forearm support includes resilient cushioning material located under the user's forearms that forms around downwardly facing areas of the user's forearms to provide even distribution of pressure on the user's forearms during operation of the user input area of the user interface device.

DETAILED DESCRIPTION

The various features and advantageous details of the subject matter disclosed herein are explained more fully with reference to the non-limiting embodiment described in detail in the following description.

FIGS. 1-4 show a user P in a conventional seated position when working in a defined location in front of the user P. In the illustrated embodiment, the user P is shown seated at a work surface W (which may be any other generally upwardly facing surface) that supports a monitor M having a display that is viewed by the user P. The user P interacts with a user input or interface device, shown at D, which may be a keyboard, touchscreen or any other input or interface device, which interacts with a computer, server or the like that outputs to monitor M. The device D may also be a laptop or notebook computer, a controller such as a game controller, or any other type of device that involves manual operation by a user.

A cushioned support arrangement in accordance with the present invention, shown generally at 100, is positioned between the device D and the user P, for supporting the forearms of user P during use of the device D. Generally, the cushioned support arrangement 100 includes a support member 101 having a forwardly arranged arm support portion 102 and a rearwardly arranged device support portion 104. In the embodiment shown on Sheet 1, the arm support portion 102 and the device support portion 104 are illustrated as being continuous and integral with each other. It is understood, however, that the arm support portion 102 and device support portion 104 may be separate members secured together or not, or that may be separated from each other by a space or gap, or may have other configurations than the integral and continuous structure as illustrated. The arm support portion 102 defines an upwardly facing surface 106 that is adapted to receive and support the forearm areas of the user P, and a downwardly facing surface 107 that faces and rests on the upwardly facing surface of work surface W. Similarly, the device support portion 104 defines an upwardly facing surface 108 on which the device D is positioned, and a downwardly facing surface 109 that faces and rests on the upwardly facing surface of work surface W. The front edge of the arm support portion 102 may include a front bumper 110. In the illustrated embodiment, the front bumper 110 has a thickness greater than that of arm support portion 102. The upper area of bumper 110 may extend slightly above the upwardly facing surface 106 of arm support portion 102, or alternatively may be flush therewith. The lower area of bumper 110 may extend below the downwardly facing surface 107 of arm support portion 102, defining a shoulder 112. The downwardly facing surface 107 and shoulder 112 may define an angle that corresponds to the angle defined by the edge of work surface W, so that shoulder 112 faces and engages the side edge of work surface W. In the illustrated embodiment, the angle between downwardly facing surface 107 and shoulder 112 is a right angle that corresponds to a right angle defined by the edge of work surface W relative to its upper surface, although it is understood that the shoulder 112 and work surface edges may have any other desired orientation and configuration.

In accordance with the present invention, at least the arm support portion 102 of support member 101 is formed of a resilient cushioning material that provides a certain amount of “give” under the weight of the forearms of the user P. Representatively, the cushion material of arm support portion 102 may be a foam material that cradles and supports the forearms of user P while maintaining the forearms above the upwardly facing surface of work surface W. The material of arm support portion 102 may be a flexible polyurethane material, such as a gel memory foam material. The material may be made of a single layer or multiple layers, which can be varied to provide desired support characteristics. The arm support portion may be provided with a skin that separates the user's skin from the foam material, or alternatively may have an outer layer of fabric or other material. Representatively, the area of arm support portion 102 that is intended to contact the user's forearms may be made of a material that can be cleaned and washed. It is understood, however, that the cushioning material of arm support portion may be any other satisfactory cushion material as desired. Examples include, but are not limited to, other foam materials, liquid materials, gel materials, polymer materials, bead materials including microbeads, feather or down materials, pellet materials, beanbag materials, seed materials, wool, horsehair, buckwheat, shredded foam or rubber, silk, hemp, etc., or any combination thereof. The internal cushion material of arm support portion 102 may be homogenous throughout the interior of arm support portion 102, or alternatively may be formed of different layers of cushioning materials or areas of cushioning materials that provide different degrees of support and resiliency at different locations along the length of the user's forearms.

In the illustrated embodiment, the arm support portion 102 and device support portion 104 are formed integrally with each other, so that the area of device support portion 102 around device D also provides resilient, cushioning support for the forearms of user P as the user P moves his or her hands to various positions around device D, it is understood, however, that the device support area 104 need not necessarily have the same cushioning characteristics as arm support area 102 and instead may have a more rigid, firm construction. The front bumper 110 may be formed of the same type of material as arm support area 102, or alternatively may be formed of any other satisfactory material that provides a comfortable support for the rear portions of the user's forearms. As shown in FIGS. 1-4, the upper surface of the device D is generally flush with, or slightly elevated above, the upwardly facing surface of arm support area 106. With this arrangement, the user P can rest a majority of the length of his or her forearms on the arm support portion 102 when operating device D, with little bend of the user's wrists being required.

FIGS. 4-8 show user interaction with the device D using the cushioned support arrangement 100, in which FIGS. 7 and 8 are section views showing support of the user's forearms. In FIG. 7, it can be seen that the arm support portion 102 is depressed under the weight of the user's forearms and that the cushioning material of arm support portion 102 conforms to the contours of the user's forearms, to provide forearm support in the area between device D and the user's elbow. As shown in FIG. 8, the cushioning material of arm support portion 102 gives under the weight of the user's forearms and provides cradling support not only under the user's forearms but also around the lower side areas of the forearms. By selecting the appropriate cushioning material(s), arm support portion 102 can provide even, cradle-type pressure distribution throughout the length of forearm engagement with arm support portion 102, to provide a very comfortable, resilient arm support that significantly reduces stress and fatigue. Arm support portion 102 has a length that is sufficient to support the majority of the length of the user's forearms during use of the device D. The forearms are thus allowed to remain generally stationary so that the user need only move his or her hands at the wrists while operating device D. The forearms are thus supported from below during use of the device D, which takes the weight of the user's arms off the shoulders to prevent stress and fatigue that would otherwise be experienced. The width of the arm support portion 102 is sufficient to accommodate a variety of arm positions throughout the width of the device D and outwardly thereof, wherever a user would normally position his or her arms during use of the device D.

In FIGS. 1-8, the device D is illustrated as an all-in-one keyboard arrangement, which includes both a keyboard and an integrally constructed touchpad or mousepad. FIGS. 9-12 illustrate a cushioned support arrangement 100 a that is constructed similarly to support arrangement 100 as shown and described previously, but in which the keyboard and a computer mouse surface are separated from each other. In this version, the supported devices include a keyboard K and mousepad MP, which may be separate components that are engaged with and supported on a cushioned support arrangement 100 a, or alternatively may be secured to and/or integrated with support arrangement 100 a. As described previously, the cushioned support arrangement 100 a provides support for the user's forearms between the edge of work surface W and the keyboard K and mousepad MP during use of the keyboard K and operation of a computer mouse CM on mousepad MP.

FIGS. 13 and 14 illustrate the difference in support of the user's arms between a conventional prior art wrist support arrangement (FIG. 13) and the cushioned support arrangement 100 of the present invention (FIG. 14). As can be appreciated, the cushioned support arrangement 100 of the present invention provides even, low pressure along the length of the user's forearm as opposed to a single, concentrated high pressure point as in the prior art. With a prior art wrist support as shown in FIG. 13, the weight of the user's arms is suspended from the shoulders and the wrist support provides a concentrated pressure point.

FIGS. 15-17 illustrate another embodiment of the cushioned forearm support of the present invention, in the form of a cushioned support arrangement 100 b. This embodiment includes a support member 101 b having an arm support portion 102 b similar to arm support portion 102 described previously. In this version, a device support portion 104 b is contoured, as is device D mounted thereto. The contour of device support portion 104 b may take any satisfactory or desired form, and in the illustrated embodiment has a generally curved or convex configuration with a raised central portion and side areas that slope downwardly therefrom. It can be appreciated, however, that the device support portion 104 b may have any other contour as desired to achieve desired ergonomic properties. A mousepad area MP may be incorporated in the device support portion 104 b, if desired.

FIGS. 18 and 19 illustrate a cross-section of the cushioned support arrangement 100 b as shown in FIGS. 15-17. The cross-section shows that the central portion of device D is elevated relative to the arm support portion, shown at 102 b. The side areas of device support portion 104 b on either side of the center slope downwardly, as shown in FIG. 17, to provide a contoured, ergonomic interaction with the user's hands. The areas of arm support portion 102 b are similarly contoured to provide comfortable, distributed arm support during use of device D.

FIGS. 20 and 21 illustrate use of the cushioned support arrangement 100 of the present invention in combination with a walking or treadmill desk system. As shown in FIGS. 20 and 21, a treadmill desk system is generally known to include a work surface W that is supported in any satisfactory manner, such as via legs L (which may be adjustable in height) that extend between work surface W and a base B. A treadmill T is positioned between the legs L, and may be interconnected with the base B or located within a space defined by base B. In a manner as is known, the user P is able to walk on the treadmill T, typically at a relatively slow speed, so as to remain generally active while working. In a known prior art arrangement, the work of user P may involve operating a keyboard or other interface device supported on work surface W, and viewing a display on monitor M. In a typical arrangement as is known, the user P rests his or her wrists on a padded wrist support S while operating a keyboard or the like supported on work surface W, as shown in FIG. 20. This provides a single point of contact to stabilize the user's upper body while walking on treadmill T, with the user P being required to bend his or her wrists on support S in order to maintain his or her fingers above the keys of the keyboard. This creates stress on the user's arms and wrist, in that movement caused by the walking motion is transferred downwardly through his or her arms that must be stabilized by the single point engagement with support S. In addition, residual movement is transferred from the user's wrists to the fingers that must be countered at the wrists, which adds to stress and fatigue.

Using the cushioned support arrangement 100 of the present invention, as shown in FIG. 21, the user P is able to rest the majority of the length of his or her forearms on the arm support portion 102 while operating the keyboard or other input device D while walking on treadmill T. This relatively large contact area, which extends in a front-rear direction parallel to movement of the tread surface of the treadmill T, greatly increases the stability of the user's upper body when walking on treadmill T and operating the interface device D with his or her hands. If desired, a relatively high friction material may be applied to the upper surface of arm support area to reduce the tendency of the user's forearms to move in a front-rear direction and thereby proved added stability to the user P while walking on treadmill T.

FIGS. 22-25 illustrate another embodiment of a cushioned user support arrangement in accordance with the present invention, shown generally at 200. As described in connection with cushioned user support arrangement 100, support arrangement 200 includes a support member 201 having a rearward area that is adapted to support an interface or input device D, such as a keyboard, and a forward area adapted to underlie and support the user's arms, more particularly the lower areas of the user's forearms rearwardly of the user's hands, which are positioned over the device D during operation of device D. In this embodiment, the support member 201 includes an array of spaced-apart retainers, shown at 202. The retainers 202 may be in the form of hook-and-loop or magnetically attractive members, such as magnets or members that are formed of a material that is magnetically attractive. In a magnetic arrangement such as this, the magnetic retainers 202 may be mounted to the upper surface of support member 201, may be embedded or positioned within recesses formed in the surface, or may be contained within the interior of the support member 201. Alternatively, the retainers 202 may be mechanical fastening components, such as half of a hook-and-loop fastening system. In an arrangement such as this, the underside of device D is provided with the mating half of such a system, such as in the form of discrete components as illustrated, or as a panel, strips or other such configuration that can selectively engage certain of the retainers 202. The retainers 202 are illustrated as being arranged in rows and columns, but it is understood that the retainers 202 may be configured in any other pattern as desired.

In the event the retainers 202 are magnetically attractive members, the device D is also provided with one or more magnetically attractive components that are attracted to the magnetic retainers 202. The magnetically attractive component(s) of device D may be in the form of one or more magnetically attractive members that are secured to the underside of device D and that are attracted to the magnetic retainers 202, e.g. discrete magnetically attractive members secured to device D such as via an adhesive or the like. Alternatively, a magnetic plate or sheet may be applied or secured to the underside of device D for engaging the magnetic retainers 202. Still further, the magnetically attractive components(s) of the device D may be contained within the interior of the device D, e.g. as part of the frame of the device D or as some other magnetically attractive component incorporated into the device D, whether or not such component is installed as part of a positioning system as shown or for some other purpose associated with the structure or function of device D.

Regardless of the specific engagement mechanism of the retainers 202 and the engaging or attracting components of device D, the user P is able to move the device D to different positions on the upper surface of support member 201 and selectively retain it in the desired position. The user can thus adjust the position of device D to any location or angle as desired, to accommodate different users or to alter the position of the device D for the same user during use.

FIG. 25 shows a flat one-piece construction of support member 201, and FIGS. 22-24 show use of support member 201 in combination with a front bumper 204. The front bumper 204 is also formed of a cushioning material as noted previously, and may be secured to or formed integrally with the front edge of support member 201. The front bumper 204 may define a shoulder that extends downwardly from the bottom surface of support member 201 so as to face and engage the front edge of work surface W, thus acting as a “hook” to maintain support member 201 in position on work surface W.

FIGS. 26-30 illustrate an angled cushioned user support arrangement 210 in accordance with the present invention, which includes a support member 211 and an arm support portion 212 and a device support portion 214. In this embodiment, the arm support portion 212 and the device support portion 214 are coplanar, and are oriented at an angle relative to the surface of work surface W so that the device D is raised and angled toward the user P. Retainers, such as shown at 216, are incorporated into the support member 211 so as to maintain device D in position. The retainers 216 may be as described above in connection with retainers 202 in the embodiments illustrated in FIGS. 22-24. In one embodiment as shown in FIG. 27, a support arrangement shown at 210 a may include a support member 211 a formed of a foam bead and gel material, and may include a depending bumper or lip that overlies the front edge of the work surface W. In another embodiment as shown in FIG. 28, a support arrangement shown at 201 b may include a support member 211 b having a similar configuration, and may be formed of a solid foam material. In another embodiment as shown in FIG. 29, a support arrangement 210 c may include a support member 211 c generally in the form of a planar member that is adjustably supported relative to the surface of work surface W via an air bladder 216, which may representatively be positioned between an upper plate 218 and a lower plate 220 that are hinged together along their front edges. With this arrangement, the air bladder 216 may be inflated or deflated to adjust the angle between the plates 218, 220, and thereby the angle of the support arrangement 210 c and device D. In another embodiment as shown in FIG. 30, a support arrangement 210 d is somewhat similarly constructed, in that it contemplates a generally planar configuration of a support member 211 d that is supported by an underlying plate 222. An adjustable leg, stand or other support, shown at 224, is positioned between plate 222 and the surface of work surface W for selectively adjusting the angle of the surfaces of support arrangement 210 d and device D. In addition to the illustrated embodiments, it is understood that any other satisfactory angle adjustment mechanism may be employed. With the embodiments of the cushioned user support arrangement shown at 210 c, 210 d, the user is able to adjust the angle of the support members and device D and the support surfaces as desired, to provide an optimum angle and support configuration for the device D and the user's arms.

FIGS. 31-33 illustrate an embodiment of a cushioned user support arrangement in accordance with the present invention, shown at 230. This version is illustrated as having a support member 231 with a configuration similar to that shown in connection with cushioned user support arrangement 100, but it is understood that other configurations as shown and described may be employed. In this version, an engagement arrangement is interposed between the work surface W and the support member 231 for positively retaining the support member 231 in a desired position on work surface W. The engagement arrangement may be in the form of magnetically attractive members 232 as shown in FIG. 31 secured to the work surface W, such as adjacent the front edge of the work surface W. It is understood, however, that the magnetically attractive members 232 may be positioned at any location on work surface W that is adapted to be positioned under support member 231 during use, and that the magnetically attractive members 232 may be incorporated into work surface W at manufacture or may be retrofitted thereto. As an alternative to the discrete magnetically attractive members 232, work surface W may also be provided with a magnetically attractive plate or strip 234 as shown in FIG. 32 at a desired location adapted to underlie support member 231. In any event, the underside of support member 231 is provided with one or members 236 that are magnetically attracted to magnetically attractive members 232 or 234, which provides releasable engagement between support arrangement 230 and the work surface W so as to retain it in a desired position and resist movement of support arrangement 230 during use. Alternatively, it is understood that a non-magnetic engagement arrangement may be employed as described previously.
